Spooky in Love — Ending Explained

The yacht. Twelve years before the story, Yeo-ri was on a yacht with Kang Ji-hwan, his adopted older brother Min-hwan, and Park Seung-jae. Ji-hwan gave Yeo-ri a protective pendant, the yacht hit a rock, and he fell overboard. Min-hwan held his hand and deliberately let go after Ji-hwan seemed to realize his feelings for Yeo-ri. Yeo-ri survived and began seeing ghosts.

The heart. Ji-hwan's heart was transplanted into Gang-uk. That explains the deep bond between Gang-uk and Yeo-ri.

Min-hwan's unmasking. Seung-jae finds the camcorder footage and blackmails Min-hwan. Min-hwan kills him and tries to frame Yeo-ri, then sends a dump truck at Gang-uk. Yeo-ri shoves Gang-uk clear and takes the impact herself.

Ending. She survives after a coma, and Ji-hwan's spirit blocks her passage to the other side. Min-hwan ends up in prison, where his mother later visits and says she will wait for him. Yeo-ri's ability disappears, and she and Gang-uk walk off together. Only after the reveal do the earlier scenes of Min-hwan's friendly concern read as possessiveness and concealment.

Viewers can read the ghosts literally, as a supernatural procedural. They can also read them as a metaphor for trauma, since Yeo-ri's ability began with survivor's guilt and ends when the truth is faced. Some reviewers felt the supernatural element faded in the final episodes as the story turned to family and corporate plots. Others see that shift as intentional: the real haunting was Min-hwan's secret.
